Abstract

The invention discloses an integrated desk-type signal simulation platform for a satellite navigation anti-interference test, and the platform comprises a control module which is used for setting scene parameters according to different performance test requirements, generating a navigation message and observation data according to a navigation algorithm, and transmitting the generated data and interference signal parameters to an FPGA; and a signal generation module which is used for generating a navigation signal and an interference signal. The platform is characterized in that, compared with the prior art, the platform achieves the simple and effective testing and evaluation of anti-interference performances of navigation receiving equipment; the platform controls a signal simulation source to generate the satellite navigation signal and the interference signal; the receiving equipment decodes the received mixed signal, and transmits the positioning speed measurement information to the control module for the evaluation of anti-interference performances.

Description

technical field [0001] The invention relates to the field of wireless communication, and more specifically relates to an integrated table-top signal simulation platform for satellite navigation anti-interference testing and a method for using the same. Background technique [0002] Satellite navigation has penetrated into communication, transportation, military and other fields, but the weak satellite signal and the openness of the navigation system make the satellite navigation system extremely vulnerable to external interference, which greatly affects the reliability and safety of navigation receiving equipment , so the anti-interference performance is becoming more and more important in the index system of navigation receiving equipment. The research and application of anti-jamming technology has greatly improved the reliability and survivability of receiving equipment, and the anti-jamming test is the main means to verify the effectiveness and application effect of anti-...
